The cable-stayed bridge is one of the most aesthetic and efficient bridge types for water crossing. However, it is infamous for its resource-taking process for analysis and design, especially the cable force tuning process. This process requires engineers to perform numerous runs of analysis after each adjustment of cable force/stress. Due to the nature of cable bridges, 3D model of a cable-stayed bridge is often very large and composed of a great number of elements and DOFs. This results in wasting many hours of high-end engineers’ hours of time for manual iteration process.

My presentation demonstrates two case studies off cable-stayed bridges which have composite deck structures. The two bridges have different scales, which is good to describe the varying levels of analysis possible in midas Civil.

I used midas Civil for overall analysis and stage checking. For more detailed checking, I exported midas Civil grillage model to midas FEA as a shell model for more detailed checking and load rating in transverse direction of extradose cable-stay bridge.
